Central and mid-peripheral corneal astigmatism in an elderly population: a retrospective analysis of Scheimpflug topography results

Scientific Reports, 2021
Implantation of toric intraocular lenses (IOLs) has become standard in the correction of corneal astigmatism. The IOL selection is based on keratometric measurements of the central cornea.

Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

Acta Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.

Duration‐Dependent Efficacy and Clinical Safety of Repeated Low‐Level Red‐Light Therapy for Paediatric Myopia: A Systematic Review and Meta‐Analysis

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Repeated low‐level red‐light (RLRL) therapy is a novel, non‐invasive intervention for controlling paediatric myopia progression. Despite increasing clinical use, questions remain regarding the magnitude, durability, and safety of treatment effects.

Polar Value Analysis of Low to Moderate Astigmatism with Wavefront-Guided Sub-Bowman Keratomileusis

Journal of Ophthalmology, 2017
Purpose. To evaluate the astigmatic outcomes of wavefront-guided sub-Bowman keratomileusis (WFG-SBK) for low to moderate myopic astigmatism. Methods. This study enrolled 100 right eyes from 100 patients who underwent WFG-SBK for the correction of myopia ...

Barriers to Ophthalmologic Care Reported by Family Caregivers of Users and Non‐Users With Intellectual Disabilities

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background People with intellectual disabilities (IDs) are more likely to experience vision‐related impairments, yet they face many barriers to accessing eye care. Although previous studies have described these barriers, few have compared barriers reported by families who have and have not accessed ophthalmologic care, which may provide ...

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Measurement of corneal astigmatism

Chinese Science Bulletin, 1998
Cornea is the most inportant optical surface in the eye dioptric system. Three kinds of methods in measuing corneal astigmeatism wre used. Three hundred and sixty eyes suffered ametropia were selected on a random basis. Computer-assisted corneal kpographic system was compared with keratometer and cycloplegic retinoscopy in measuring corneal curvature ...
